The Last of Us The Making of Documentary bug

One day booting up the game, I decided to watch the documentary. So I went into the extras menu and chose the documentary when the ps3 froze. No buttons worked, and I couldn't go out of the game. Thought to myself that it was just a simpe bug, and that I just had to restart to make it work. Then the same thing happened again. Is this just me, or is this a common problem?
